Activity 10.5.4.

In this activity we will look at the measurement of curvature and determine if curvature is a property of the driver or a property of the road. This is a continuation of Activity 10.3.3. As a reminder, a measurement is a property of the driver if the value(s) of that measurement can be different for different drivers (when measured at the same location on the racetrack). A measurement is a property of the road when different drivers must have the same value(s) (when measured at the same location on the racetrack).

🔗

(a)

Is curvature a property of the driver or the road? Write a few sentences about your reasoning and be sure to address why every driver may or may not have the same measurement at the same location on the track.

🔗

(b)

What is the curvature on a straightaway (the race track is a line segment)? What would the radius of curvature be for a straightaway? Write a couple of sentences to justify your answers.
